Over the past two decades, acquiring a tan through exposure to artificial sources of ultraviolet radiation has become popular among fair skinned people, particularly adolescents and young adults.234 The use of such tanning devices has been associated with a significantly increased risk of melanoma. Two linked research papers provide further evidence of the harmful effects of indoor tanning.56
